Twin Commander offers two new kits for owners

Twin Commander Aircraft is introducing two new Custom Kits (CK) for operators. CK 186 replaces Weldon fuel boost pumps with Parker Airborne pumps, and CK 188 adds a  filler port to the supplemental oxygen system.

When JetProp Commanders were still in production under Gulfstream Aerospace, the factory changed from Weldon to Airborne boost pumps, but the change was never offered for existing aircraft, company officials said. Now, with CK 186, the upgrade is available for the following models:

  • 690C s/n 11600 through 11729
  • 690D s/n 15000 through 15025
  • 695 s/n 95000 through 95086
  • 695A s/n 96000 through 96055

Parker Airborne pumps are preferred because of their superior reliability, and the increasingly prohibitive cost of overhauling the older Weldon pumps, according to company officials. CK 186 contains all of the parts and instructions necessary to install the Parker Airborne pump, but it does not include the pump itself, officials note.

If the Weldon pumps have already been replaced, installation of the hardware in CK 186 ensures that the upgrade meets OEM and FAA requirements and approval. The conversion to the Parker Airborne pumps should take about two hours per engine.

CK186 is in stock and ready for purchase from an authorized Twin Commander Service Center.

Twin Commander Aircraft has developed CK 188 to modify the supplemental oxygen system so the remote-mounted oxygen tank can be refilled more conveniently.

Some Commander models were delivered new with optional oxygen refill fittings that allow a technician to open an access door on the aft fuselage, unscrew a cap, and fill the supplemental oxygen bottle at the source. Without the optional filler port, the oxygen bottle must be removed, or disconnected from the aircraft system, to be refilled. This increases the potential for damage to the bottle and fittings, company officials said.

CK 188 contains the necessary parts and instructions to add the oxygen bottle fill port to the following Twin Commander Aircraft models:

  • 690A s/n 11249, and 11269 through 11349
  • 690B s/n 11350 through 11599
  • 690C s/n 11600 through 11650
  • 695 s/n 95000 through 95040

CK188 will be available this March.
